IMPROVEMENT IN DUMPlNG-CARS.

Specification forming part ofLetters Patent No. 221,577, dated November 11, 1879; application filed April 14, 1879.

To all whom it may concern:

Be it known that I, SIDNEY D. KING, of Pittston, in the county of Lnzerne and State of Pennsylvania, have invented certain new and useful Improvements in Cars; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a dumpingcar, as will be hereinafter more fully set forth.

In the annexed drawin gs, which fully represent my invention, Figure l is a bottom view of a car embodying my invention. Fig. 2 is a central vertical section of the same on line y 3 Fig. 1. Fig. 3 is a side elevation, partly in section. Fig. 4 is an end view, and Fig. 5 is a transverse vertical section on line 00 m, Fig. 3.

A represents the body of a car to be used for coal or other material that may be emptied through the bottom. The interior of the car is constructed to form inclines B B from each end toward the center, and in the center of the car-bottom is a movable door, 0. This door is provided with two shafts or axles, a a. each of which has on each end a flanged wheel or roller, b. The rollers b b run upon inclines formed in slotted castings or plates D D, which are attached to the sides of the car and depend from the same, one on each side, as shown. The inclines d d in these plates or castings are arranged in such a manner that the inner end of the door will run down an incline while opening, and the outer end will run nearly horizontal, so that the Weight of the material in the car will cause the door to open as soon as it is unlatched.

At the outer end of the door G is hinged an arm, F, which passes through a casting or plate, G, at the end of the car, and this arm is formed with a shoulder, e, at such a point that, when the door is closed, the said shoulder will catch on the plate G or on the timbers of the car, and hold the door closed. The arm is then looked in place by means of alatch, H, pivoted to the plate or casting G, and dropping down over the end of the arm. The latch B may then be locked by means of any suitable look, when the door cannot move out of place. However, when the latch H is raised and the arm F lifted up, the weight of the material in the car will cause the door to move on the incline and open to let out the material; or a slight pull on the arm F will start the door and cause it to move.

At one end of the car I use an axle, I, placed in bearings stationary with the car, and upon said axle are secured the wheels J J. Each wheel has on its inner side a flange, f, on top of which works a curved brake-lever, K. These brakes or brake-levers are pivoted to the body of the car, and their ends connected with levers L L by means of straps or links h, the said levers L being pivoted one on each side of the car-body. The outer ends of the side levers L are connected by means of a cross-bar, M, which is by a chain, 1', connected with the operating-lever N, as shown. This operatinglever is pivoted to the end of the car, so as to be easily accessible, and by the arrangement of the various parts a compound leverage is obtained, so that a slight movement of the operating-lever N will cause the brakes to exercise a powerful pressure on the inner flanges, f, of the wheels.

At the other end of the car is a truck, 0, containing one or more axles and sets of wheels. This truck is hung upon a central shaft, on, running lengthwise of the car, so that in passing around curves, where one side or line of rail is higher than the other, the truck will conform to such inclination, while the body of the car will remain comparatively level.

On each side of the car opposite the ends of the truck 0 is secured a casting, P, which has at each end a flanged projection, R, that extends down and embraces the corners of the truck, thus forming stops for limiting the rocking movement of the car-body on the truck.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a dumping-car, a central sliding door, inclined ways, and a latching or looking device connected with the door, this said door being arranged to slide on an incline automatically by the weight of the coal or like load within the car when the latching device is released, snbstantially as herein set forth.

2. The combination of the door 0, having 5. The castings P, with flanged corner projections It, formed with stops at their lower extremities, in combination with a car-body and a car-truck hung to the body on a longitudinal central shaft, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signaturein presence of two witnesses.

SIDNEY D. KING.
